' Application filed December 26, 1894.. Serial No. 532,919.. (No model.)

lie it known that l, lv'lxmn-:n Gur'rox, a citizen oi' the l'niled States ol' America, rcsiding at :San A\ntenio, in thceountvof llenar and State olf Texas, haveinvented certain new and nsetnl improvements in llows, oi' which thetollowingisaspecification,rei'ercncobeing had therein tothe accompanying drawings.

This invention relates to snlkv-plows, and aimsto provide an agricultural implement having iront and rear gronndwheels which I are irnlepenrlentl)Y adjustable vertically to regulate the depth to which the plowing can he elioeted, and which will have their standards const rin-ted to receive shovels, teeth, and earllntreating devices ol' various forms.

'lhe improvement willln` morefnllvset forth hereinafter and claimed. and is illnstratml in the aeeompnnving drawings, in which Figure l is a persiLn-clive view ol a snll\' v plow ,nnhodving i he essent ialprinciplesolfthe Fig. 2 is a detail view oL' one oi` the standards having a slotin its lowcrenrved end to ixitercliangeably"receive the various forms o1' shovels and earth-treating devices. Fig. 3 is a group ol' .some ot the forms ol' shovels, teeth, or earllrtrcatingdevices which are designed to he interchangealilbv attached to the lower end ol' any oi' the standards.

'lhe trame A oi' the device is substantiallyv A or triangular sha-pcd and has a lor\\f"ardly shaped extending bar l, lfrom which rises a tnbularpost U anda guide-l ngl 'lheclevisl pivotally connected to the l'ront end of the har l and is adapted to have the d ra tft adj ustabi)Y applied thereto. Standards ls are attached to the side bars ot the Vl'ramc and are strengthened lrv lnaces f. '.lhe lower ends ot' lthese standards enrve l'orwa rd and have a slot (1, in which is itted and secured one of the various l'orms and shapes ol' shovels and teeth shown in Fig. 3. rlhe rearedges oi' the shovels have anotch G,i'ornxing side cxtei1sions,whieh project on each side oi' the standard to brace the shovel against lateral stress, so that a single bolt sni'tices to secure the shovel to the standard.

lln liig. 3, l reln'escnts a double-turn plow; 2, a scraper; 3, a sod-cnttcigl, a single-turn plow and coltcr combined, and 5 a rake or harrow tooth. An)r one ot' these devices can be interchangeably attached to a standard to meet the requirements of the character of the worlcto be performed. A sha-ft or brace 1I is jonrnaled inthe rear oi the frame in bearings T and hasparallcl arms h projectfing at right langles therefrom, in the lower ends of which are jonrnalcd ground-whcels l. An upwardlv-entended arm J is attached by link 8 to lever lx', by mea-ns of which the shaft ll is turned in its bearings to raise or lower the ground-wheel l to regulate the depth of the plowing. A pawl 71, carried by the lever K, engages with one of a series of notches in the seg-ment M, so as to .hold the said lever li in theflocatcd position. The front ground-wheels N are mounted in frames n, which are jonrnaled in sockets o at the ends of a crossbar O. ly this arrangement the groinnl-wheols adaptthclnsclves to the direction ot' the draft. 'lwo slotted standards l projet-1 verticallylrom the cross-bar t ),.and are connected at their upper ends by a cap-piece l), which is centrallyaperturcd to receive the shank of a bearing Q, to which is pivoted a lever R., These standards 1 are disposed in parallel relation, one on cach side ot' the bar l. The ends oi' the lug I) extend into the sl ots ot' the standards l and guide them intheirvertical movements. Links S connect the forward ends of the lever R with the forward portion ol' the bar l. A pivotcd bar T, located near the drivcrs seat, has notches to receive a portion of a keeper on Athe end of the said lever to hold the latter in the desired position. The head U has a st cm or pin by means of which it is pi votall y connectedwith the tubular post C. An arm Y is pivoted to the head U.

ly raising and lowering either or both sets ol' gronml-whecls the shovels can be regulated to plow deep or shallow'as required.

.l claiml. ln `a snlky plow the combination of a frame having a forwardly extending bar l, provided with a .vertically disposed lug l), whose ends project beyond the edges of the bar 13, a crossbar O, having ground wheels and vertically arranged slotted standards P, occurring on opposite sides of the bar B, and receiving the projecting end portions of the lng l), a lever mounted upon the connected ends of the slotted standards, and links connecting the lever with the bar l5, substantially as described.
